Eighteen miniatures, the final six sketched in but unfinished, by an accomplished artist whose identity remains uncertain. The miniatures are usually framed in a pink or mauve egg-and-dart molding and a thin gold band. Dedicatory inscription in gold Roman letters on a marble-patterned panel appears on f. 7r. One historiated initial, below inscription, 10-line, of the author at work: gold, edged in black, against a purple and pink quartered ground with pink and purple filigree; all framed in green. In lower margin, supported by putti, is the coat-of-arms of Ferdinand of Aragon, King of Naples.
